3(5x + 2) = 2(3x - 6)<br><br> Step by step please give me the right answer . Thank u
Solnce55 [7]

Answer:

x = -2

Step-by-step explanation:

3(5x + 2) = 2(3x - 6)

<em>Expand the brackets. </em>

15x + 6 = 6x - 12

<em>Isolate the unknown variable x. </em>

15x - 6x = -12 - 6

<em>Evaluate. </em>

9x = -18

<em>Find x. </em>

x = -18 ÷ 9

x = -2

What is the y-value of the vertex of the function f(x) = –(x – 3)(x + 11)?
Mrrafil [7]
Expand
f(x)=-1x^2-8x+33

x coordinate of vertex is -b/2a in the form ax^2+bx+c=y
a=-1
b=-8
-(-8)/2(-1)=8/-2=-4
plug back in to get y value

y=-(-4^2)-8(-4)+33
y=-16+32+33
y=49

y value is 49

a state charges an 8.5% sales tax and a 10% excise tax on gasoline. he purchased $25 of gasoline before tax. How should he find
Mama L [17]

Answer:

The total money spend on total tax of purchase is $4.625

Step-by-step explanation:

Given as :

The percentage of sales tax applied on gasoline purchase = 8.5%

The percentage of excise tax applied on gasoline purchase = 10%

The price of gasoline before tax = $25

Let The total money on total tax of purchase = $x

Now, Total percentage of tax = sales tax percentage + excise tax percentage

i.e  Total percentage of tax = 8.5% + 10%

Or,  Total percentage of tax = 18.5%

<u>Again</u>

total money on total tax of purchase = $25 of total total tax percentage

Or, x = $25 × 18.5%

Or, x = $25 × \dfrac{18.5}{100}

Or, x = $25 × 0.185

∴  x = $4.625

So,The total money on total tax of purchase = x = $4.625

Hence,The total money spend on total tax of purchase is $4.625 Answer

FOR 12 POINTS I NEED HELP ASAP! Consider the system of linear equations. 5 x + 10 y = 15. 10 x + 3 y = 13 To use the linear comb
Romashka [77]

Answer:

Do you mean which equation should the 5x+10=15 be multiplied to?

it would be -2

Step-by-step explanation:

This is because 5 times -2 is -10

and so when you add the (now) x value of the first equation to the x value of the second equation, it gets 0

which makes it eliminated!

-10x+10x=0
